Abstract

The utility model discloses an aluminum alloy pipe wrench used to clamp and rotate pipe workpiece, comprising a movable jaw and a small jaw, and the small jaw is connected at the front end of a movable support, and a hand clasping is arranged in the movable support. Besides, a rack is inserted into the hand clasping, and the front end of the rack is connected with the back end of the movable jaw, and the back end of the rack is connected with an aluminum sleeve. Instead of the adjusting nuts, the hand clasping of the movable support is meshed with the rack to adjust the clamping diameter of the jaw so as to release quickly. Meanwhile, a plurality of working procedures for producing the parts of the adjusting nuts and the screw thread of the movable jaw can be eliminated in the manufacturing process and the working productivity can be improved. The utility model has the advantages of light weight and material saving.

Description

Aluminium alloy pipe pincers

Technical field

The utility model relates to a kind of pipe vice that is used for clamping and rotation steel pipe class workpiece.

Background technology

Known pipe vice comprises moving jaw and little jaw, and little jaw is fixed on the front end of claw beam, is connected with the knurled nut between claw beam front end upside and the moving jaw rear end.Match by trapezoidal thread between moving jaw and the knurled nut.Its regulative mode is by regulating the knurled nut, moving jaw is moved forward and backward the clamping diameter of regulating jaw, thereby governing speed is slow.

Summary of the invention

The purpose of this utility model is the aluminium alloy pipe pincers that will provide a kind of governing speed fast.

The purpose of this utility model is achieved in that this pipe vice comprises moving jaw and little jaw, little jaw is connected the travel(l)ing rest front end, and the attacker is arranged in travel(l)ing rest, and tooth bar inserts among the attacker, the tooth bar front end links to each other with the moving jaw rear end, and the tooth bar rear end links to each other with the aluminium grip.

The utility model does not have adjusting nut, but adopts in the travel(l)ing rest engagement between the attacker and tooth bar to regulate the clamping diameter of jaw, realizes getting loose fast.Simultaneously, reduce operations such as manufacturing adjusting nut parts and moving jaw cutting thread in process of production again, improved production efficiency.In light weight, conservation.

Description of drawings

Fig. 1 is the structural representation of an embodiment of the utility model.

1. moving jaws among the figure, 2. little jaw, 3. travel(l)ing rest, 4. tooth bar, 5. attacker, 6. aluminium grip.

The specific embodiment

In Fig. 1, this pipe vice comprises moving jaw 1 and small forceps mouth 2, small forceps mouth 2 is connected travel(l)ing rest 3 front ends by hollow pins, attacker 5 is arranged in travel(l)ing rest 3, tooth bar 4 inserts among the attacker 5, tooth bar 4 front ends link to each other by rivet with moving jaw 1 rear end, and tooth bar 4 rear ends and aluminium grip 6 link to each other by rivet.

Moving jaw 1 and small forceps mouth 2 have all adopted steel alloy to forge and formed, and handle making the crown hardening by high frequency, and be can holding workpiece firm, durable.

Travel(l)ing rest 3 and aluminium grip 6 have adopted the manufacturing of aluminum alloy materials material, have alleviated overall weight.

Tooth bar 4 adopts the quality carbon steel cold drawing molding, and tooth bar 4 tooth punching portions adopt high frequency to handle.

Attacker 5 adopts quality carbon steel to be stamped to form.

Claims

1. an aluminium alloy pipe clamps, and this pipe vice comprises moving jaw and little jaw, it is characterized in that little jaw is connected the travel(l)ing rest front end, the attacker is arranged in travel(l)ing rest, tooth bar inserts among the attacker, and the tooth bar front end links to each other with the moving jaw rear end, and the tooth bar rear end links to each other with the aluminium grip.
